[Acid-base equilibrium of fetuses delivered by breech presentation]. 1976

S Lipenský, and A Neuwirth

Acid-base balance of fetus in capillary and umbilical blood has been examined in two series of newborns: 30 newborns delivered by breech presentation and 15 newborns delivered spontaneously by vetex presentation without complications. Following parameters have been evaluated: pH, pCO2, BE and HCO3 (actual bicarbonate content). Differences between the parameters of acid-base balance, mainly the values of pH and pCO2 in capillary blood and in a. umbilicalis of the fetus direct to the fact that acidosis of the fetus with elevated values of pCO2 is a typical finding in labors by breech presentation and is due to compression of umbilical vessels during labor.

D007746	Labor Presentation	The position or orientation of the FETUS at near term or during OBSTETRIC LABOR, determined by its relation to the SPINE of the mother and the birth canal. The normal position is a vertical, cephalic presentation with the fetal vertex flexed on the NECK.

D001946	Breech Presentation	A malpresentation of the FETUS at near term or during OBSTETRIC LABOR with the fetal cephalic pole in the fundus of the UTERUS. There are three types of breech: the complete breech with flexed hips and knees; the incomplete breech with one or both hips partially or fully extended; the frank breech with flexed hips and extended knees.
